Recent advancements in the synthesis of Veratrum alkaloids

The Veratrum alkaloids constitute a class of natural products with particularly intricate polycyclic frameworks and dense stereochemistry and, thus, have stood long as benchmarks in chemical synthesis. Recently, these steroid alkaloids gained popularity as challenging targets in total synthesis, with a clear shift toward convergent strategies. Not only do these syntheses feature rapid assembly of their challenging cores through modular and strategic bond connections, but they also give a reflection on the advancement of modern synthetic methods and retrosynthetic logic. This review will cover recent syntheses, highlighting the convergence of modern strategic disconnections, stereocontrol, and late-stage functionalization for rapid access to these exceptional alkaloids, while also showcasing the evolution of the art of synthesis and its ability in meeting the demands posed by molecular complexity.
